Speed vs. Velocity Confusion
Students often confuse speed with velocity, thinking they are the same because both are related to how fast something is moving.
To fix this, remember that speed is a scalar quantity with no direction, while velocity is a vector quantity that includes direction. Always specify the direction when discussing velocity.
